Method, device and system for providing additional information related to the contents of a radio broadcast to terminal devices

ABSTRACT

A radio broadcast system using a second communication channel provides an interactive functionality to allow a user to know what song or piece of music is playing on the first, radio channel and possibly other details about what is being listened to. A data transmission from the broadcast station is received by a server with additional information about the content of the first channel, and after the server determines mobile terminal devices to be updated with the additional information, it generates updating messages comprising the additional information, and updates the information to the determined terminal devices via a wireless communication network. The updated information is then received by a given terminal device and displayed on a display of the device.

The invention is related to the field of traditional radio broadcast.The invention is more specifically related to radio broadcast having aninteractive messaging service. Most specifically the invention isrelated to a radio broadcast system using a second communication channelto provide an interactive functionality. The invention is designed toenhance the listening comfort of the user. The invention allows the userto know what song or piece is playing on the radio channel and possiblyother details about what is being listened to.

A person listening to a radio broadcast often has need for additionalinformation about current programs, e.g. the song playing in the radio.There are some known methods of providing this:

-   -   The original solution is that the radio DJ recites the name of        the music track and maybe the artist at the end of a track    -   Different radio stations are able to provide information via        “radio data system” (RDS) known from car radios    -   Different internet radio stations are able to provide        information about their current show through their home page    -   Nokia™ has published a collaboration with Capital Radio™        (London) using an interaction and information service via SMS

The first two classical solutions do not provide an interactive radio,as there is only a one-way connection from the radio station to thereceiver. The two classical solutions have the drawback that certain andmaybe useful options cannot be used in a one-track-only environment. Themain drawback for the DJ is that he does not always tell the name of thepiece and of the artist of a music track. The main advantage is that anyuser can hear the announcements of a DJ, without the need for specialequipment

The main drawback of the Radio Data System is that the standard RDSradio display is too small to provide a sufficient space to display thename of the radio station, the artist and the name of the actual track.The information is provided in a newscaster-fashion on a very smalldisplay. Especially in car radio applications, the reading of thenewscaster consumes time and distracts the attention of the driver fromthe traffic while driving. Another drawback is that actually only a fewradios are equipped with an RDS system.

Different Internet radio stations are able to provide information oftheir current show through their home page. The use of the Internetincludes the use of a two way communication medium, which in turnprovides a fully-fledged interactivity or adds interactive features to aconventional radio station. With the use of an additional two-waycommunication channel, interactive features are added to thefunctionality of a conventional radio station. The main drawback of thissolution is that the user needs a computer and has to be online which isin fact time, energy and money consuming.

The SMS (Short Message Service) based information service of Nokia™ incollaboration with Capital Radio™ offers a conventional radio stationwith an interactive component by using SM (Short Messages) as anadditional two-way communication channel, to transport additionalinformation between the listener and the radio station and vice versaTherefore, a user can interact with the radio station by sending an SMto the radio station. The additional information can comprise requestedadditional information of an actual track, a notification of anotherperson when a certain track is going to be broadcast on a certain radiostation, or the transfer of a ringing tone for a mobile telephoneincluding the tune or the chorus of the track actually broadcast.

The SMS (Short Message Service) based information service has thedrawback that the user has to request the information by sending an SMto the radio station, which is expensive. Another disadvantage is thelimited input device (the ITU-T keypad) as the SMS has to be typed firstbefore being sent. The short message service is only capable ofdelivering one single item of information.

The SMS based information service has the drawback in that the userneeds a possibility to send an SM to the radio station. Usually this isdone by means of a mobile telephone, which includes the drawbacks thatthe user may not be certain which radio station he is actually listeningto, and to which radio station the SM is to be sent. This problem can beavoided by a classical broadcast radio facility integrated in a mobilephone terminal such as in case of Nokia 5510™, 6510™, 6590™, 6610™,7210™ and 8310™.

All the above approaches have in common that they are not suitable toprovide an optimized data transfer from a radio station to a user.

Therefore, it is desirable to have an optimized data exchange between auser device and a radio station without a waste of network resources.

It is further desirable to have a system that is easy to use and inwhich an incorrect operation is almost excluded and impossible.

It is further desirable to have a system capable of selectivelydelivering additional information to a certain user.

According to a first aspect of the present invention a method isprovided for delivering additional information data related to thecontents of an actual radio broadcast from a radio station to terminaldevices, wherein the terminal devices are connected to a server in awireless communication network. The method may be used in a server in awireless network and comprises the reception of a data transmission fromsaid radio station. Said data transmission comprises additionalinformation data related to the actual contents of a radio broadcastfrom said radio station. The additional information data can compriseinformation such as the name of artist, composer or the name of a pieceof music, the author and the name of a radio play, and other backgroundinformation. The information data can be plain text, as e.g. in the caseof RDS/SMS compatible information, but can also comprise graphics,pictures and advertisements. Another possibility is to use a URL link.This can be embodied in a later release of presence in the dynamicphonebook. This opens up the possibility of interaction with a webbrowser if even more info is required. The additional information caneven comprise a small acoustic intro of the song, or, an animatedpicture sequence like used in the magic latern, or even a small videosequence. After the reception of the transmission, the server can storeor update the information in the server.

Following the reception of said transmission, the server determinesmobile terminal devices to be supplied or updated with said additionalinformation. This can be embodied by means of a relation tablecomprising a list of all terminal devices to be delivered with saidadditional information. Then, the server generates an updating messagefor each of said determined terminal devices comprising said additionalinformation. The server can also generate a single updating message forall or groups of the determined terminal devices comprising saidadditional information data, and adapt only the respective addresses.The size, the format, and even the information contents of the messagemay be custom-generated for each of said determined terminal devices independence of the properties of the destination device or informationstored in the relation table. The messages can be generated independence of a transfer protocol used in said wireless communicationnetwork. Finally, the server sends said generated messages to each ofsaid terminal devices via said wireless communication network.

It is to be noted that the single transmission needs not to be requestedor confirmed, but can be received as in case of a one-way pager. Theterminal devices may confirm the transferred message. Therefore, it ispossible that the server further receives a message from the wirelessnetwork or a terminal device to stop the transmission. It may be notedthat the time required to deliver the message to the terminal deviceshould only require a few seconds, and should not exceed a minute. Afast delivery of the messages is required as the actual radio broadcast,e.g. a piece of music has an average duration of a few minutes, and incase of longer delivery time the additional information is no longer upto date and invalid concerning the contents of the actual radiobroadcast transmission.

In one example embodiment, said server uses a presence database fordetermining said mobile terminal devices to be supplied with saidadditional information. A presence database is e.g. known from messagingprograms in the Internet informing a user about the other selected usersbeing online or not. One aspect of the invention is that of a presencefeature. Presence has many definitions. The one used here may be:“Presence” is a dynamic (variable) profile of a user, visible to othersand used to represent oneself, share information and control services”.This embodiment of the invention proposes an innovative use forpresence, which goes beyond the standard definition. This functionalitycan best be compared with internet messaging programs comprising “buddylists” indicating if certain persons are online or not.

In this embodiment of the present invention, this feature is extended tomore and more specific information, such like the title of the actualtrack, the title of the CD or the name of the artist. Instead ofpresence entries such as “I'm here” or “I'm happy” the Radio stationprovides the information “(I'm playing) U2—Beautiful Day” as thepresence entry of the radio station. In a second step, this informationis forwarded to all terminal devices having subscribed to thisinformation, or listed the radio station in their “buddy list”. So acontinuous and actual data transfer from the radio to the terminaldevices via a simple server using standard components can be achieved,without the need to start repeated information transfer from the user tothe radio station to request this information.

In another example embodiment, the method further comprises adetermination, whether or not said additional information received fromsaid radio station has changed, and generating said messages only, ifsaid information has changed. By using a simple comparing step of thereceived information, the server can suppress the generation ofredundant messages and save network resources of said wireless network.

In yet another example embodiment, the method further comprisesreceiving a transmission from a terminal device indicating that saidmobile terminal device is to be supplied with said additionalinformation. Following that, a message comprising said additionalinformation for said terminal device is generated and sent to saidterminal device via said wireless communication network.

By receiving the transmission from the terminal device, the server canprocess or change the presence status of said terminal device, e.g. bychanging entries in a relation table to recognize this device as anaddressee for a message containing said additional information. By thefollowing two steps, the server generates and delivers a message to saiddevice comprising the actual additional information. This procedureguarantees that a user receives the actual information immediately, whensubscribing to the information service. This procedure describes thetransmission of the first message to a terminal device with is thenupdated by the following messages form the server.

In yet another example embodiment of the present invention the methodfurther comprises the reception of a transmission indicating that saidmobile terminal device is no longer to be supplied with said additionalinformation. This transmission can be originated form the device itself,to cross off or delete the subscription to said service. In another casethis information can be originated from a server of said wirelessnetwork indicating that the terminal device is not longer connected tosaid network.

According to another aspect of the present invention, a method fordisplaying additional information data related to the actual contents ofa radio broadcast from a radio station is provided. In this method saidadditional information is received from a server via a wirelesscommunication network, and comprises: receiving said radio broadcastfrom said radio station via a wireless broadcast channel, receiving amessage comprising said additional information data from a serverconnected to said wireless communication network and displaying saidadditional information from said received message.

The received messages can be delivered form a push-type service, bygenerating the messages, as is described in the preceding description.The method can further process data contained in said message fordisplaying said data The received data can be stored and be updated witheach newly received message. An updating process can comprise storing anactual data transmission and deleting a previous data transmission. Thestorage can contain a single entry or a number of the last 2, 3, 5 or 10entries, so a user can look at the title of a song heard a few minutesago. The memory can be implemented as a first-in-first-out memory with aselectable storage depth. The user can transfer the additionalinformation to a “task memory” to remind him to buy the CD from which heheard a song.

With this solution, the user would only have to subscribe once to theradio station. The track information for the radio station would then beupdated automatically in the user presence list, which is a list at theuser device indicating the presence of other user and the radio station.In the case of Nokia™ terminals, this information can be updated in thephonebook. In addition, the information is not just limited to text, butcan also comprise graphics and other media types. This leaves anopportunity for extra information or branding on behalf of the radiostation. This embodiment of the present invention proposes to treat aradio station as “typical presence presentity”. In this way, a user cansubscribe to the presence of the radio station in the standard way. Thedifference is that the radio station would use different presenceattributes from a normal user. Instead of typical presence attributessuch as availability (online/offline) and mood (happy/sad) the radiostation would use an attribute, which has e.g. the value of the currenttrack playing on the radio.

In another example embodiment of the present invention, the methodfurther comprises processing said additional information of said messagefor display and/or for storage. This processing can be used to compressdata to reduce the required storage space. This processing can forexample be used to generate animated display content, to adapt coloredgraphics information to a black and white display.

In yet another example embodiment of the present invention the methodfurther comprises transmitting a message to a server in said wirelesscommunication network to initiate the transmission of a messagecomprising said additional information related to the contents of saidreceived radio broadcast. This can be embodied by subscribing to apresence database, a presence notification service and the like.

In another example embodiment the method further determines a name ofsaid radio station transmitting said radio broadcast A table allocatingeach frequency to a radio station entry can perform this determination.An RDS system can determine the radio station automatically, by using aninaudible component in the radio broadcast transmission to transfer thename of the radio station to the user terminal. In a more sophisticatedembodiment of the invention, the terminal device itself canautomatically generate a subscription message and join the additionalinformation service after user confirmation.

In yet another example embodiment of the present invention, the methodfurther comprises the displaying the name of said determined radiostation, and said received additional information together on a display.Both information can be displayed in a “split screen” fashion, and in acomposed graphic comprising information received from a radio module anda wireless network module.

According to yet another aspect of the invention, a software tool isprovided comprising program code means stored on a computer readablemedium for carrying out the method for providing additional informationrelated to the actual contents of a radio broadcast from a radio stationto a terminal device of the preceding description when said softwaretool is run on a mobile terminal or a network device.

According to another aspect of the present invention, a computer programproduct for carrying out the method for providing additional informationrelated to the actual contents of a radio broadcast from a radio stationto a terminal device of the preceding description is provided, whichcomprises downloadable program code means for performing all of thesteps of the preceding description when said program is run on a mobileterminal or a network device.

According to yet another aspect of the invention, a computer programproduct is provided comprising program code means stored on a computerreadable medium for carrying out the method for providing additionalinformation related to the actual contents of a radio broadcast from aradio station to a terminal device of the preceding description whensaid program product is run on a mobile terminal or a network device.

According to another example embodiment, a network server for providingadditional information related to the contents of a radio broadcast froma radio station to connected terminal devices is provided. The networkserver comprises a network module for receiving transmissions comprisingsaid additional information from said radio station. The network modulecan connect the server to a wired or a wireless network. The networkserver comprises a database for storing indications of said terminaldevices to be supplied with said additional information This databasecan be embodied as a presence database, to provide a presence serverfunctionality to the server. A controller is connected to said networkmodule, for processing said received transmissions, and is connected tosaid database for receiving indications of said terminal devices to besupplied with said additional information and for generating messagesand updating messages for said determined terminal devices. Thecontroller can be configured to operate the server as a presence server.The server further comprises a wireless network module for sending saidgenerated messages to said terminal devices.

The network module and the wireless network module can be integrated ina single device if the connection to the radio station is alsoimplemented as a wireless connection. The implementation involvesintegrating a presence server and the infrastructure of the radiostation. This integration can be done using the OMA (Open MobileArchitecture) interface. This entails that a presence service operator(e.g. mobile operator) exposes the interface to the radio station. Thiscan be done via SOAP/HTTP so that this can be switched over theInternet.

In yet another example embodiment, the present invention provides amobile terminal device, that is capable of displaying additionalinformation related to the actual contents of a radio broadcast from aradio station. The mobile terminal comprises a radio module, a wirelessnetwork module, a controller, a memory and a display module. The radiomodule is for receiving said radio broadcast. The wireless networkmodule is used for receiving messages and updating messages comprisingsaid additional information. Said controller is for processing saidreceived messages and updating messages connected to said wirelessnetwork module. Said memory is connected to said controller for storingand updating said additional information. The display module isconnected to said controller for displaying said additional and updatedadditional information. Such a terminal device can be presence enabled,meaning that the terminal device can run a presence software on saidcontroller to receive and handle messages indicative of the presencestate of other terminals in said wireless network.

In another example embodiment of the present invention, said radiomodule is connected to said controller, and said radio module isconnected to said wireless network module to transfer data from saidradio module to said wireless network module. The connection can beimplemented as a direct connection to said wireless network module or asan indirect connection via said controller module. In contrast to theabove embodiment, wherein said radio module can be implemented as aseparate module within said mobile terminal device, a data exchangebetween the radio module and the wireless network module is enabled.This connection can be used to control the radio directly from thecontroller. Another advantage of this connection is that a user can usea single interface to operate all the functions of the radio, thewireless network module and the other components of the mobile terminaldevice.

In another example embodiment, said radio module comprises a radio datasystem (RDS) module for determining said radio station. By using an RDSradio, a user can easily recognize the radio station he is listening towithout the need to remember on which frequency a certain radio stationoperates. The RDS radio in connection with the network module can beused to automatically generate the message to subscribe to thenotification service, or can be used to automatically configure thepresence service.

In another example embodiment, the mobile terminal device furthercomprises a cellular telephone module connected to said controller. Thecellular phone module enables the device to provide a multipurposefunctionality to a user. With such a multi functional device a userneeds only to carry a single device instead of a number of differentdevices to listen to radio broadcast, hear music, access a wirelessnetwork and to phone other people.

In yet another example embodiment the mobile terminal device furthercomprises a television module being connected to said controller. Byincorporating a TV in the mobile terminal, a user can utilize theadvantageous features of a wireless network connection to be providedwith additional information related to the actual TV program. This canbe especially useful e.g. for the transfer of additional informationsuch as subtitles and actual news.

Further, the invention in another embodiment comprises a system forproviding broadcast data, said system comprising

a broadcast station for sending a broadcast and for providing additionalinformation data related to the contents of said broadcast;

a network server for receiving said additional information data, saidadditional information data to be supplied to at least one mobileterminal device, said network server comprising:

-   -   a network module for receiving said additional information data        from said broadcast station,    -   a database for storing indications of said at least one mobile        terminal devices to be updated with said additional information        data,    -   a controller being connected to said network module, for        processing said additional information data, and being connected        to said database for receiving said indications of said at least        one mobile terminal device and for determining at least one        mobile terminal device to be supplied with said additional        information data, and    -   a wireless network module connected to said controller for        updating said additional information data with said determined        mobile terminal device, and

a mobile terminal device capable of displaying said additionalinformation data, comprising:

-   -   a radio module for receiving said broadcast,    -   a wireless network module for receiving said additional        information data,    -   a controller for processing said received additional information        data, said controller being connected to said wireless network        module,    -   a memory connected to said controller for storing said processed        additional information data, and    -   a display module connected to said controller for displaying        said processed additional information data.

The system in accordance with the present invention comprises thebroadcast station, the network server and the mobile terminal device.

It is to be noted that the mobile terminal device can compriseadditional modules such as a media player/recorder, a digital camera andthe like.

In the following, the invention will be described in detail by referringto the enclosed drawings in which:

FIG. 1 is a graphic showing the basic components of system architecturefor executing the method of the present invention.

FIG. 2 depicts the architecture of FIG. 1, with indications of the datatransfers necessary for executing the method according to the invention.

FIG. 3 is depicts the architecture of a terminal device according to oneembodiment of the present invention.

FIG. 1 shows a high level outline of the architecture of the system.There are three basic elements, the user terminal 2, the Presence Server8 and the radio station infrastucture 6. Other elements are omitted forsimplicity. The protocol 16 between the terminal 2 and the PresenceServer 8 is the Wireless Village Client Server Protocol (CSP). Theprotocol 16 between the terminal 2 and the Presence Server 8 can also beembodied as SIP SIMPLE. The protocol 14 between the Presence Server 8and the radio station infrastructure 6 is the Presence Server WebServices interface. In the figure, the terminal 2 comprises a display 4.The Presence Server 8 is connected to a Wireless Village transmissionstation 10. The radio station infrastructure 6 is transmitting a radiobroadcast 12. The display 4 of the terminal is depicting the name ofradio station that is actually received. In as classical multi purposedevice this can be achieved by a RDS or a manually generatedfrequency/Radio Station correlation, as in the case of phone bookentries of a mobile phone. To implement the present invention aconnection 14 between the radio station infrastructure 6 and thePresence Server 8 of a wireless network is required. The wirelessnetwork is necessary to keep up the mobility of the mobile multi-purposeterminal device 2.

FIG. 2 shows a simple use case of a radio station 6 playing a track 20.1and then updating the track info 22.2, 24.4 e.g. in the subscribersphonebook. The user subscribes to a track information service bytransferring or notifying (18.3) the server 8 to subscribe to a presenceservice of the radio station 6. With the broadcast of a new track 20.1,the radio station 6 transmits changed presence information 22.2 to thepresence server 8. Following that, the presence server determines allterminal devices having subscribed to this service and sends messages24.4 to all terminal devices containing additional information of theactual track. The track info is updated via the Wireless Villagetransmission station 10 using the Wireless Village free text attribute.The track info also updates the logo attribute in the mobile terminaldevice 2 to place a picture 26 of the band playing.

The invention makes use of different aspects of presence. Between theuser terminal and the Presence Server a client server presence protocolsuch as Wireless Village or SIP SIMPLE can be used. Between the radiostation and the Presence Server, the Presence Server Web Service API(Application Protocol Interface) is used. This can be embodied as aproprietary interface, but can also be implemented as part of the OMA(Open Mobile Architecture) Web Services. In practice, the radio stationsimply updates its presence using the OMA API and the Client Serverprotocol ensures that this information is relayed to the user terminal.

This invention presents a way to provide additional information of thecurrent radio show (or other broadcast) by the means that the radiostation is the presentity in presence server. The listeners who want toadd the radio station to their “buddy list”, “dynamic phonebook” etc.are able to check the radio station status when ever they want to. Theradio station status comprises the actual track information andadditional features. The status is updated to their terminalsautomatically as known from the SIP SIMPLE or Wireless Village protocol.

The present invention provides two major advantages: the amount of datapushed to the devices is reduced and requires only a minimum of networkresources, and the invention can be implemented using only standardapplications such as messaging systems, not requiring feedback.

In addition to the transfer of the additional information the wirelessinterface to the radio station via the server can be used to provideadditional interactive features to:

-   -   Dedicate a track to a friend, who will be alerted to the        dedication 15 minutes before the track is played on the radio        station. Dedications can be accompanied with a text greeting        from the sender.    -   Set an alert for himself to provide a reminder function not to        miss a certain show on radio or TV.    -   Find out the name of both the last track and the track currently        playing, along with the name of the artist, current price        information for the CD at a local music store.    -   Select and download new tracks as ringtones directly from a        server or the radio station using their mobile phone.    -   Additional services such as gig guides, news and alerts for        on-air features are also envisaged.

The current invention improves earlier solutions in terms of usabilityand convenience. To give a comparison with the SMS based service, theuser in that service has to send an individual SMS for each track herequests information about. Moreover, for each request the user has totype in his request as an SMS message. Then, the information returned isrestricted to a text only format.

FIG. 3 is depicting the architecture of a terminal device according toone embodiment of the present invention. The terminal device 2 comprisesa display 4, a controller 34 connected to the display. The controller 34is further connected to a memory device 38, to a wireless network module32, a broadcast receiver module 30 and to a telephone module 36. Thecontroller 34 is also connected to a user interaction interfaces (notshown) such as keys, keypads, microphones loudspeakers and the like tocontrol the modules 30 to 38. The centralized architecture of thisembodiment enables the device to use only a single memory module 38 tostore all the relevant data from the telephone 36, the wireless network32 and the broadcast module 30. This enables the device 2 tosimultaneously display data from the radio module 30 (i.e. the stationname depicted in upper area of the display 4 indicated by a dottedarrow) and the additional information received via the wireless networkmodule 32 (i.e. the picture 26 depicted in the lower area of the display4 indicated by a dotted arrow). The present invention is not restrictedto the above displayed architecture, but can be modified in differentways, to be extended with additional modules for receiving TVbroadcasts, play and record media, digital cameras or video recordersand the like.

The usage of the invention is much easier than the one with SMSmessages. Also compared to the Internet Radio systems it does notrequire a continuous data connection, which is a quite resource wastingmethod particularly in mobile solutions. The information is pushed tothe terminal only when the presence information has changed.
